Expression data from the rat knee articular cartilage at different developmental stages

ABSTRACT: Age as the primary rise factor could be play an important role in incidence and development of osteoarthritis. Several studies have confirmed some tissue specific microRNA were associated with development of osteoarthritis. But if age related microRNA or miRNA cluster would be involved in pivotal post-transcriptional gene regulation in osteoarthritis is unclear. In view of this, we have an idea that several age-related miRNAs would be screened from the rat knee cartilage at different development ages by miRNAs Microarray analysis. We used microarrays to detail the global programme of gene expression underlying the rat knee cartilage and identified distinct classes of age-related miRNAs during this process.

Expression data from the rat knee articular cartilage at different developmental stages

Several studies have confirmed some tissue specific microRNA were associated with development of osteoarthritis. But if age related microRNA or miRNA cluster would be involved in pivotal post-transcriptional gene regulation in osteoarthritis is unclear.

We used microarrays to detail the global programme of gene expression underlying the rat knee cartilage and identified distinct classes of age-related miRNAs during this process. The rat knee articular cartilage were selected at successive stages of the rat developmental for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain homogeneous populations of cartilage at each developmental stage in order to increase the temporal resolution of expression profiles. To that end, we hand-selected cartilage according to the rat developmental stages, i.e. seven time-points: newborn (T0), childhood (T1), youth(T2), adult (T3), middle-aged (T4) early-stage elderly(T5) and latter-stage elderly(T6). The objective of the study is to identify miRNA profile of knee articular cartilage at different developmental ages in rats. Total RNA were extracted from the knee articular cartilage of Sprague-Dawley rats at postnatal day 0(T0), week1(T1), week 4(T2), mon3(T3), mon 6(T4), mon 12(T5), and mon 18(T6). The microRNA profile in the specimens was detected with the Affymetrix GeneChipÂ® miRNA 3.0 Array.

Expression data of LncRNA from the rat (Sprague-Dawley) knee articular cartilage at different developmental stages

Osteoarthritis-related changes in gene expression in knee articular chondrocytes in a rat model of osteoarthritis.

Project description:Cartilage destruction in osteoarthritis (OA) results from disturbed chondrocyte metabolism. Here, we used microarrays to show that TGF alpha and CCL2 are simultaneously upregulated in a rat model of OA and cooperate to drive cartilage degradation. The goals of the experiments included here were to a) characterize gene expression in knee joint articular chondrocytes at various stages of development of OA (2 and 8 weeks after surgical induction of OA), and b) to establish trends in gene expression among groups of genes related to the TGF alpha-EGFR axis, over time, in OA. The model chosen to study these results has been previously validated (Appleton, CT et al, 2007, Arthritis Rheum) and used to describe similar gene expression results at a different time point (4 weeks) after induction of OA. The rat model of OA involves surgical destabilization of the knee joint, followed by forced low-intensity mobilization over several weeks; a sham surgery is used as the control (representing a healthy non-OA knee joint) wherein a surgical incision is made but not structural (i.e. ligamentous) modification is made to the joint. Altogether, our data indicate that TGF and CCL2 cooperate to drive cartilage degradation in osteoarthritis.

RNA-Seq analysis of human osteoarthritic intact cartilage following total knee replacement

Project description:Large scale RNA-Seq analysis was performed to investigate the transcriptomic response to osteoarthritis in cartilage and investigate potential subgroups of patients. Data were collected from intact knee cartilage (posterior lateral condyle) from at total of 60 patients with osteoarthritis (OA) following total knee replacement and 10 control non-OA patients following amputation.

RNA-Seq analysis of human intact and damaged osteoarthrtitic cartilage following total knee replacement.

Project description:This experiment captures the expression of genes between two sites of human cartilage within the same patients to allow investigation of genomic responses to damage during osteoarthritis. Eight patients with symptomatic OA undergoing total knee replacement (n=8, age range 65-79 years, mean age 70.3) were used in this study. Cartilage from paired osteochondral samples were isolated from the intact PLC (posterior lateral condyle) and the damaged DMC (distal medial condyle) for RNA-seq analysis.

Investigation of miRNA expression signatures in mTORC1 -stimulated osteoarthritis

Project description:To further explain pathology of mTORC1 -stimulated osteoarthritis, we have employed whole genome microarray expression profiling as a discovery platform to identify miRNAs which involved in development of mTORC1-stimulated osteoarthritis We generated Col2a1-specific deletion of Tsc1 mice. mTORC1 induced miRNAs expression in development of osteoarthritis was measured at eight weeks after birth. Independent experiments were performed using knee joint cartilage from Col2a1Tsc1KO and control mice.
